AUTOMATIC TRAIN-PIPE COUPLING.

class known as side couplings, such as, for eX- ample, the construction shown in my prior patent, No. 582,672.

Couplings of this character are brought into enga ement by a longitudinal movement, the oint gaskets being kept apart until in alinement, then a lateral movement is ermitted, which brings the gaskets toget er.

The pipe sections are pressed together in this position by a yielding resistance means in order to malntain a tight joint. OrdmarIly this construction operates satisfactorily, but

in cases, asfor example, when the coupling sections are subjected to a Severe tilting strain, the sections may rock on each other in such a way as to open the joint and permit air leakage, in s ite of the yielding resistance device.

It is t erefore the principal object of my present invention to provide means to resist the tendency to lateral movement of the coupling sections other than the usual and normal movement effected in coupling and uncou ling.

In t e accompanying drawings, Figure 1 is a plan view of an automatic pipe coupling, showing the two half sections coupled together, with one form of my improvements applied; Fig. 2 a similar view with another form of my invention applied; Fig. 3 a similar view wlth aslightly modified form of my invention applied; Fig. 4 an elevational view of the face of one of the half sections of the coupling as shown in Fig. 3; Fig. 5 a plan view of an automatic pipe coupling, with still another form of my improvement ap lied; Fig. 6 a side elevation of'one of the ha f sections of the coupling shown in Fig. 5, and Fig. 7 an elevational view of the face of one of the half sections.

Referring toFig. 1 of the drawings, the cou ling comprises the ipe sections 1 and 2, eac having an inclines guide surface 3 for directing the sections into proper coupling position. provided with a spring 4, and theback of the outer end is inclined to form a sliding hearing The inner end of each'section is for the spring 4, sothat the sections are 'eldingly held together as they approac the coupled position, and in that position. This 5 in each sectlon to engage corresponding grooves in the outer section, for the pur ose of preventing the gaskets from rub ing agalnst each other'in coupling and uncoupling, as described in my prior patent above referred to.

According to the form of my improvemerits shown in Fig. 1, I provide curved catch plates 6, the inner faces of which are adapted to engage the'foremost nose portion 11 of the inclines 3, said faces being preferably inclined at approximately the same angle as the beveled engaging surfaces 7 of the tongues 5. The catch which fastens the spring 4 in place. The nose end of the incline 3 may also be beveled to correspond with the inclined surface of the catch plate.

In making a coupling connection, as the sections approach allnement the beveled surface of the tongues 5 engage the corres 0nding beveled surface of the groove an also the nose of the incline 3 with the catch plate,"

so that when the parts are in the coupled position, any tendenc of the joint to rock and open up is effective y resisted by the engagement of the nose on the inclined surface of the catch plate. It will be noted that while the tendency to tilt or to move laterally is resisted there is no interference with the normal operation of coupling and uncoupling.

According to the construction shown in Fig. 2, I provide each section with a spring plate 8, which may be arranged within the usual s ring 4 and having the outer end portion a apted to engage the guide incline of the spring intermediate the nose and the oint of contact of the spring 4, so that a ateral o ening movement of the joint is resisted, 1i e the construction Shown in Fig. 1, as will be obvious.

In Figs. 3 and 4 is illustrated a modified form of my invention similar to that shown in Fi 1. In'this case I provide lugs 9, inte ra with each of the coupling sections, and a( apted to engage corresponding slots 12 in the adj accnt section, the contacting surfaces of both slot and lug being preferably at the same angle as the bevels 7 of the ton ues 5. Two such lugs are preferably provi ed on I form of coupling is also provided with tongues lates 6 may be secured in position conveniently by the rivet 8 each coupling section. The operation beingsubstantlally the same as that of the construction shown in Fig: 1.

Still another construction is shown in Figs. 5 to 7 inclusive, wherein each section is provided with laterally projecting lugs 10,v adapted to engagecorrespondmg lug s on the other section, and having the engaging faces thereof beveled at preferably the same angle as the tongues 5.

It will now be apparen that by means of my improvements thecoupling joint is se-r curel and firmly maintained, and leakage is there y prevented, as lateral'movement .or tilting o the section is prevented. It will also be apparent that the liabilit of a coupling to open and permit leakage, y reason of pipe section in the ooulpledposltlon, to there- .mg the sections together in the couple y resist movement 0 sections tending to open the coupling .joint laterally.

2. An automatic pipe coupling, comprising two sections adapte for ongitudinal engagement, a yielding spring device for ressposition, and means attached to one'p'ipe section reslstance means for pressing the sections adapted to engage the other section and thereby resist lateral movement of the sections other than the normal uncoupling movement. 3. An automatic pipe coupling, comprising a pi e section, adapted to couple with a compamon section upon relative longitudinal movement, a spring device attached to the pipe section for yieldingly pressing the coactingsections together, an means secured to each pipe section adapted to engage the companion. section to resist relative lateral movement of saidhead's.

4. An automatic ipe coupling, comprising two pipesections a apted to couple together upon longitudinal movement relative to each other, a spring deviceon each pipe section for yieldingly pressing said sections together, and means secured to onep' gaging the companion section to-resist relative lateral movement of said heads.

5. An automatic pipe cou(pling, comprising two ipe sections adapte to be coupledtoget or by a preliminary longitudinal movement and a final lateral movement, a spring device attached to each section for yieldmgly pressing the sections together and means secured to each section a apted to engage the companion section free movement in the direction of said final lateral movement, but adapted to resist other lateral movement.

- In testimony whereof I have'hereunto set my band.
